Currently, as you're still very much presenting as a woman, albeit a hirsute one, maybe you should focus your marketing  around that - they are lots of men who enjoy hairier women, so advertise as having a full bush, hairy armpits and that you don't shave your legs.

I don't think it is possible for you to advertise as a trans male until you have had surgery, because until you do, you still have the body of a biological female. Also, be prepared that working as a trans male (FtM) will be incredibly niche, and there might not be any takers, although for some men, I suppose it will be an experience to tick off. You mention having bottom surgery. Will you be having a phalloplasty? If you are, it would be worth waiting to see how functional your penis will be. It is worth noting that Buck Angel didn't have a phalloplasty because it is impossible to make a penis that is comparable to a biological one, and instead, he kept his vagina and is known as a 'Man with a pussy'.

It is worth checking out Birchplace although I do not know if there are any FtM escorts, particularly ones that are fully transitioned.

Hth, and good luck with everything.

Hi everyone, I have been working for about 2 years as a woman, but am in fact a transgender man. I'm taking testosterone and my voice is starting to break and I'm getting hairy, I'm not really sure what to do? I want to get both top and bottom surgery, but these are both very expensive.
Where is good to advertise myself as a trans man? I'm on adult work and it doesn't seem to have any other trans men on there, and I'm worried people will think I'm a trans woman (clients aren't very understanding)
Are there any other trans men on here who can give me advice working as a guy? I'm happy to work as a woman until I get rid of my boobs, but after that there'll be a big wait before I get a penis. Please help!

There are loads of transgender men doing videos and other content from what I have seen, some have not had bottom surgery but either way make money. Like TMM said though, as far as escorting long term goes it might not be as profitable.
